Ternary Amorphous Solid Dispersions Containing a High-Viscosity Polymer and Mesoporous Silica…
The aim of this study was to evaluate the benefits of a ternary amorphous solid dispersion (ASD) that was designed as an immediate-release tablet with a high drug load (e.g., 40% w/w) to produce heightened maintenance of drug supersaturation during dissolution testing, which will be henceforth…

Evaluation of different pre-processing methods of X-ray micro computed tomography images
Adequate images of real tablets provide the possibility to validate in silico software tools like F-CAD. The goal of this work was to evaluate the influence of different pre-processing methods of X-ray micro-computed tomography images of 12 different tablet batches. The images were processed with…

Impact of polymer type, ASD loading and polymer-drug ratio on ASD tablet disintegration and drug…
Amorphous solid dispersion (ASD) has become an attractive strategy to enhance solubility and bioavailability of poorly water-soluble drugs. To facilitate oral administration, ASDs are commonly incorporated into tablets. Disintegration and drug release from ASD tablets are thus critical for achieving…

Overcoming the Solubility Barrier of Ibuprofen by the Rational Process Design of a Nanocrystal…
Wet media milling, coupled with spay drying, is a commonly proposed formulation strategy for the production and solidification of nanosuspensions in order to overcome the solubility barrier of BCS Class II substances. However, the application of mechanically and thermally intensive processes is not…

3D printing of extended-release tablets of theophylline using hydroxypropyl methylcellulose (HPMC)…
An extrusion based 3D printer was used to prepare the semi-solid tablets with different drug loading dosages (75, 100, 125 mg) under ambient temperature. The active pharmaceutical ingredient, theophylline, was uploaded within the hydrogels prepared of hydroxypropyl methylcellulose (HPMC) K4M or E4M.…
